摘要
从喷洒有除草剂的土壤中分离到一株能分解膦化麦黄桐(PPT)的细菌.该菌在以PPT为唯一碳源的培养基上生长,能利用PPT的最高浓度为2. 7g/L.采用常规生理生化鉴定方法,并结合16SrDNA序列分析法对该菌进行鉴定.结果表明,该菌与生癌肠杆菌(Enterobactercancerogenus)序列相似性为99. 3%,在细菌分类学上属于肠杆菌.将它命名为Enterobactersp. PPT.
One bacterial strain degrading L -phosphiothricin (PPT) was isolated from soil sprayed with herbicide. The strain could grow on medium containing PPT as sole carbon source and resist PPT with concentration up to 2.7 g/L. In addition to general physiological and biochemical properties, the strain was identified by 16S rDNA sequence and systematic analysis. The results showed that 16S rDNA sequence of the strain had similarity of 99.3% with that of Enterobacter cancerogenus , suggesting that the strain belong to Enterobacter . The strain was nominated as Enterobacter sp. PPT. Fig 4, Tab 2, Ref 7
